Unconventional high-temperature superconductivity from repulsive interactions

It is shown that the Cooper pairing in the states with small angular momenta is strongly suppressed with the realistic Coulomb repulsion between fermions at relevant temperatures in any dimension.

Energy-gap dynamics of superconducting NbN thin films studied by time-resolved terahertz spectroscopy

Using time-domain terahertz spectroscopy we performed direct studies of the photoinduced suppression and recovery of the superconducting gap in a conventional BCS superconductor NbN.

Current-voltage characteristic of narrow superconducting wires

We have shown that the anomalies in the current-voltage charachteristics are connected with bifurcations of stationary or oscillatory solutions.
